VALVE.

To all 'whom it concern:

Be it known that I,`FRANK P.4 MoReg, Ya 1 citizen of the UnitedStates, residing at cinnati, in the county of Hamilton and State 5 of Ohio, have invented new and ,useful Improvements in Valves, of which the followinais a specification. y invention relates to valves and more partlcularly to the class called check valves of the automatic plate t pe which are peculiarly adapted to be use in connection with 'any fluid or gas distribution apparatus, gas engines, blowers, compressors, or pumps.

The objects of myA invention are to construct a valve of the character above re fer-red to which is 'adapted to be used', if so desired, in connection with or operate upon a plurality of luidsor gases and devised to eliminate all springs, and be most reliable and eicient in its action under all and valried conditions of operation.

A' furtherV object of the invention is to form avalve of the class 'above pointed out which comprises a simplicity of anda minimum number of parts, low cost of production, easily assembled or taken apart, and no parts subJected to bending, torsional ortensile stresses, thereby not only increasing the life of the valve but at the same time insuring the constant and uniform operation of the same under all fluctuations of'pressure and velocity of the gases or fluids in passing through the valve.

Other objects ofthe invention will appear from the detailed description of the construction andoperation of the valve to be hereinafter given.

The invention consists of structural characteristics and relative arranfgements of elements which will be hereina er more fully appended claims.

In the drawings 10 represents the valve sea-t which as shown is preferably made rectangular or square inv formbut anyfother shape or contour, as circular may be adopted without departing from the essential `features of the invention. r

Said seat lOis provided with a seriesl of central ports 11, 11 separated by bridge sections 12, 12, said ports communicating with f an inclosed middlecham'ber'13 having inlets 14, 14, either one of which inlets may be plugged or closed --ii so desired.

. -In said seat 10 and oneach side of the ports 11, 11, and in line therewith, are pro` -vided other ports 15, 15, separated by bridges 15', 15', which ports lead to lateral chambers 16, 16, open preferably atvtheir bottomand arranged on each side -of the chamber 13, said' chambers 13 and 16, being separated by walls 17, 17 as shown in Fig. 5.

18 is a valve ide" plate o r cover which likewise is provlded with a series of separated ports or slots 19, 19, and bridge sections 20, 20, and is secured by-means of properly arranged screws or bolts 21, 21 to the to'p of the valve seat 10, in such a position that its ports 19, 19, are disposed'between the ports 11, 11 or over the solid metal bridgesor sections 12, 12 in the top of the valve seat 10, as clearly shown in Figs'. 3 and 4, thus bringingthe solid or bridge sections v 20, 20 of the valve guidepIat'eor cover 18 properly over the ports 11 and 1 5 ofthe valve seat 10,' and arranging the ports 19 ports 11 and 1-3 in a staggered relation. l

On the underside and opposite ends of the bridges 20, 20, of thevalve guide plateor cover 18 and corresponding to the alinement of the ports 11, 15 of thevalve seat 10, are cut orv cast a series of shallow recesses 22, 22 as shown in Figs. 2, 3' and 4, opposite reA to loosely receive a flexible and yielding valve plate 2 3, shown in detail in Fig. 6, for purposes to be presently disclosed, and while theends of thevalve plates 23 are shown square or rec'- tangular 4in shape and the coperating recesses 22, 22 are correspondingly formed,

any other shapej as semi-circular, may be readily substituted without departing from the spirit or changing the operation of the lnventlon. For the valve plates 23, 23 toward and rmly holding them against the seat 1 0 after the same purpose of' quickly drawing` the" stantly drawn back by the magnetic action of the valve seat 10, thereby insuring a quicker and tighter closing of the valve duri ing the operation of the same.

The ports of the valve being arranged as shown in Figs. 3 and fi, the operation is as The chamber 13 by means of inlets 14 and chamber 16 by means of its 'lower openings being in communication with and connected to supplies of luid or gas, when an 'exhaust action is eEected in the upper face of the valve guide plate 18, tending to draw said fluid or gas through the valve, 'the flexible valve plates 23, 28 are simultaneously and uniformly lifted from the seat 10 y until they abut against the underside of the bridges 20, 20, of the plates 18, thus permitting the fluids or gases to be drawn from the chambers 18 and 16 through the .ports 11 and 15 into the ports 19, 19 to be thoroughly mixed and carried to the point of consumption, and as soon as the suction ceases and the 'pump' or flow of the liquid or gas is reversed, said iiexible plate valves 23 are quickly and tightly seated against the seat 10 and over the ports 11 and 15, due to their iexibility thereby insuring not only a quick action of the valve but at the same the minimum per cent. of leakage or slippage due .to the very low lift or movement ofthe valve plates and their capability to yield to the exact )contours or(- planes of the valve seat at each of the ports 1L and 15.' While I have .shown my valve as adapted te be used in connection with two flu-ids or gases, the same is readily adapted to be operative in connection with one or a lurality of iiui'ds or gases and can be used in any position whether vertical, horizontal or at an angle.

From the foregoing disclosure of the construction and operation of the valve, it will be readily seen that all the objects ofthe invention previously pointed nut have been fully carriedv out and no parts of the valve are subjected to bending stresses, entirely free in action without friction or other disturbing forces and capable of acting Vupon onlyone gas, air or liquid, or mixing two or more gases or li uids.

A mixing valve comprising a valv seat having a series ofports and e, plurality of separate and independent chambers coms municating with one of the open ends of said ports, a valve plate cuide supe-rimposed on said valve seat 'an contiguous to the other open ends of said valve seat ports and having a series of ports in communication with said valve seat ports, a series of independent valve plates'loosely and freely interposed between said`\. valve seat and valve plate guide and so constructed and arranged as to be adapted tobe firmly seated on the valve seat over each of the valve seat ports, or lifted against the underside lof the valve plate guide to establish communication with the valve seat ports and ports of the valve plate guide and said chambers.
